提交后 就出现这种异常报告
------解决方案--------------------
空指针异常啊，可能是你JSP某个地方的代码写错了。检查一下。
java.lang.NullPointerException
------解决方案--------------------
到你的tomcat的 work目录下找到display_jsp.java文件
88行，这里 没有得到你想要的值，为null.然后自己判断是display这个jsp哪行出现了问题。如果判断不出来就用打印语句一句一句打。找出出错的地方。
------解决方案--------------------
java.lang.NullPointerException
跟踪一下，可能是servlet或者jsp页面里面有错误。
